=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- PHASE II for Program STSI 05B-14 (PI Paul Goudfrooij). =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- SCHEDULED DATE: Nov 7th, 2005 Start with grating 47 setup 47/Ic, see below. Note the non-nominal slit width. Please make sure the collimator focus setting is correct. Name Slit Filter Coll Grating Tilt & Comp,exp Ystart Ysize Yspec Blaze w.l. cov.

Make sure they are well exposed but not saturated at any location. Here is the target list. The NGC targets are all globular clusters. Get well-exposed TWILIGHT SPECTRA at zenith at beginning of night. Aim for 3 spectra, each with between 5,000 and 30,000 counts per pixel.

Times mentioned assume the observing night to be Nov 7th, 2005. Start observing targets after taking twilight spectra, say 20:40. DO NOT FOCUS TELESCOPE YET! THE TELESCOPE SHOULD BE OUT OF FOCUS FOR THE FIRST FOUR STARS! HR 8610: Target is bright star. - After pointing, center star on slit. NO GUIDING! - Take 10 s Neon lamp comparison exposure - Set "guide" mode motion at 1 arcsec/sec - After starting a 60 sec exposure, move star along the slit in "guide" mode in one direction (say West) until the exposure is finished. Time should be ~20:50 (sid time ~22:15) HR 8697: Target is bright star. - After pointing, center star on slit. NO GUIDING! - Take 10 s Neon lamp comparison exposure - Set "guide" mode motion at 1 arcsec/sec - After starting a 60 sec exposure, move star along the slit in "guide" mode in one direction (say West) until the exposure is finished. Time should be ~21:00 (sid time ~22:25) HR 8772: Target is bright star. - After pointing, center star on slit. NO GUIDING! - Take 10 s Neon lamp comparison exposure - Set "guide" mode motion at 1 arcsec/sec - After starting a 120 sec exposure, move star along the slit in "guide" mode in one direction (say West) until the exposure is finished. Time should be ~21:10 (sid time ~22:35) HR 8795: Target is bright star. - After pointing, center star on slit. NO GUIDING! - Take 10 s Neon lamp comparison exposure - Set "guide" mode motion at 1 arcsec/sec - After starting a 60 sec exposure, move star along the slit in "guide" mode in one direction (say West) until the exposure is finished. Time should be ~21:20 (sid time ~22:45) - FOCUS TELESCOPE. A good target to do so might be SAO 214109, a V=10 mag star [RA(2000.0) = 22 49 19.18, DEC(2000.0) = -30 26 05] Time should be ~21:35 (sid time ~23:00) Feige 110: Target is Flux standard star.

DO NOT GUIDE! - Take 10 s Neon lamp comparison exposure - Set "guide" mode motion at 1 arcsec/sec - After starting a 150 sec exposure, move star along the slit in "guide" mode in one direction (say West) until the exposure is finished. Time should be ~06:00 (sid time ~07:25) HR 2154: Target is bright star. - After pointing, center star on slit. DO NOT GUIDE! - Take 10 s Neon lamp comparison exposure - Set "guide" mode motion at 1 arcsec/sec - After starting a 90 sec exposure, move star along the slit in "guide" mode in one direction (say West) until the exposure is finished. Time should be ~06:10 (sid time ~07:35) HR 2701: Target is bright star. - After pointing, center star on slit. DO NOT GUIDE! - Take 10 s Neon lamp comparison exposure - Set "guide" mode motion at 1 arcsec/sec - After starting a 120 sec exposure, move star along the slit in "guide" mode in one direction (say West) until the exposure is finished. Time should be ~06:20 (sid time ~07:45) HR 2874: Target is bright star. - After pointing, center star on slit. DO NOT GUIDE! - Take 10 s Neon lamp comparison exposure - Set "guide" mode motion at 1 arcsec/sec - After starting a 60 sec exposure, move star along the slit in "guide" mode in one direction (say West) until the exposure is finished.
